Conclusions : at present , endoscopic sphenoidotomy is the mainstay of treatment for isolated sphenoid sinusitis 但有免疫缺陷疾病者，容易并发眼窝和颅内合并症，预后较差。
Conclusion : we show here that sphenoid sinus mucocele can simulate a variety of pathological conditions 由于它在我们眼科的临床表现可以是外展神经麻痹及逐渐视力丧失，因此应将它列入?别诊断。
An incidental finding at autopsy , this light tan colored meningioma involved the sphenoid ridge , another common location 尸检中偶然发现的位于蝶骨脊处的脑膜瘤(左上) ,它是脑膜瘤的另一个好发部位。
The natural ostium of the sphenoid sinus can usually be identified medially to the tail of the middle turbinate , approximately 1 cm above the choana 蝶窦的自然口通常位于中鼻甲的后部，后鼻孔上缘
Conclusions ： nasal endoscopic and imaging study is very important for the diagnosis and surgery of lesions in isolated sphenoid sinus neoplasm 结论：鼻内窥镜、影像学检查对本病的诊断起重要作用，并对手术有指导意义。
Purpose : here we examine a case of sphenoid sinus mucocele presenting with left abducens nerve palsy and subsequent loss of left eye vision 摘要目的：报告一例因罹患蝶窦黏液囊肿而导致单侧外展神经麻痹及视力丧失的病例。
With early diagnosis and prompt surgical intervention , the sphenoid sinus mucocele - associated neurological deficits can be restored completely 惟有早期诊断及手术治疗，其所导致的外展神经麻痹及视力丧失才有可能完全恢复。
In all cases , the isolated space - occupying lesions in sphenoid sinus were verified by ct scan , and biopsies were made under nasal endoscopy before operation 恶性肿瘤4例，包括蝶窦低分化鳞癌2例，腺样囊性癌1例，内翻性乳头状瘤恶变1例。
Method : to analyse eleven cases with cerebrospinal fluid rhinorrhea , pituitary tumor , encephalomeningocele , sphenoid sinus cyst and ethmoid sinus tumor , were analyzed from 1998 to 2004 and beening followed up for 6 months to 6 years 方法：分析我科1998年~ 2004年间经鼻内镜手术治疗脑脊液鼻漏、垂体瘤、鼻内脑膜脑膨出、蝶窦囊肿、筛窦癌等，资料完整、随访时间为6个月~ 6年的病历11例。
Subtle changes , such as polyps in the early stages , can easily be identified . purulent secretions are seen streaming here from the maxillary sinus ostium posteriorally towards the nasopharynx . posteriorally , medial to the tail of the middle turbinate , the ostium of the sphenoid sinus may be identified 能很容易的发现类似早期息肉等微小的病变，还可以显示脓性分泌物从上颌窦口向后流向鼻咽部和后方的中鼻甲的后段和蝶窦的开口。
